coulombs law states that "the force acting on point charges is directly proportional to yhe product of charges q1 and q2 and inversely proportional to thr square of the distance between the two charges".
(point charges means charges whose size is negligible to the distance between them)
F=kq1q2÷r^2
k=constant whose value is 9×10^9
hope my answer will help u

The law. Coulomb's law states that: The magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them. The force is along the straight line joining them.
The Formula. Coulomb's law describes the force between two charged particles. Here, F is the force between the particles, qa and qb are the charges of particles a and b. The separation between the particles is r, and k is a constant, 8.99x109 (Nm2/C2).
